IMPROVEMENT IN SCAFFLD-BRACKETS.

Specification forming part of Letters Patent No. l 59,309, dated February 2, 1875; application filed November 14, 1574.

To all 'whom t may concern:

Be it known that I, SAMUEL N. FISHER, of Milford, in the county of Vorcester and State of Massachusetts, have invented a new and useful Improvement in Sca-ftbld-Brackets, of which the following is a specification:

This invention relates to apparatus for supporting scadolds for the erection of buildings; and consists of a folding bracket having an adjustable hook for fastening it to the building, the construction being as hereinafter de-4 scribed.

In the accompanying drawing, Figure is a sectional side elevation of the bracket, showing it arranged as when in use. Fig. 2 is a View ofthe bracket detached from the building, and folded up when not in use.

Similar letters of reference indicate corresponding parts.

A represents the building. B is the stand of the bracket, which is placed in contact with the building. C is the bearer, which is connected with the stand B by iron straps D on each side, the straps being bolted or riveted to each part, so as to turn on the bolts or rivets and form a joint. E is the brace. This brace is stepped into mortises at each end, as seen in the drawing, and its upper endis connected with the bearer C by means of a strap,

F, upon each side, fastened by bolts or rivets to the parts, so as to serve as a ljoint. Gis the hook by which the bracket is held to the building. The hook is attached to the bearer G by means of the fast nut-piece H, through which the hook passes. There is a screwthread on the hook, which engages With a screw-thread in the nut-piece H. The screw is turned in or out, to accommodate the thickness of the wall or timbers of the building. The hook is attached to the wall when the bracket is folded; then the bearer and the brace are put in position, and the bracket is ready for the scatold-plank.

When not in use the. bracket is folded as seen in Fig. 2, and occupies but little space.

Having thus described my invention, -I claim as vnew and desire to secure by Letters Patent- 1. The adjustable hook G and nut-piece H, in combination with a scaffold-brach et, for the purposes described.

2. The straps D and F, in combination with the parts of a scaffold-bracket, as and for the purposes described.

SAMUEL NELSON FISHER.
